ALLEN HAWORTH, OF MABTON, WASHINGTON.

WEEDER R CULTIVATOR.

T0 all whom it may concern Be it known that I, ALLEN HAWORTH, a

` citizen of the United States, residing at Mabton, in the county ofYakima and State of l/Vashington, have invented certain new and usefulImprovements in Weeders or Cultivators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such asV will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to weeders or cultivators and has for one of itsobjects the production of a device for eiiiciently cultivating theground for the purposeof eradieating the same of all obnoxious weedscontained therein.

A further object of this invention residesV in the construction of aweeder or cultivator for efficiently destroying obnoxou weeds regardlessof the foulness of the A still further object of this invention is theprovision of means for preventing the machine from becoming choked withthe foul grasses, etc., which may be upon the land. And a still furtherobject of this invention resides in the provision of means forefficiently locking the revolving knives against rotation formaintaining certain of the same in operative position. And anotherobject of this invention resides in the provision of means foreiiiciently adjusting the locking means for regulating the depths of thecutting knives relative to the ground and the .further provision ofmeans for retaining the locking means out of engagementV with therevolving knives, whereby the cultivator may be readily transported fromone ield to another.

These and other objects will more fully appear and the nature of theinvention more clearly understood, by the construction, combination andarrangement of parts thereof as described in the followingspeciiication, dened in the appended claims and illustrated in theaccompanying drawings, in which,

Figure 1 is a perspective view ofthe weeder or cultivator showing thesame in its complete form ready for operation, Fig,

Specification of Letters Patent.

Patented June 22, 1915.

Application filed April 7, 1914. Serial No. 830,181.

2 is a fragmentary detail view, partly in section, illustrating themanner of mounting the adjustable locking means showing the same inengagement with one of the cutting knives for preventing the rotation ofthe wheels and knives.

Referring to the drawings, 1 denotes the side bars of the frame, 2 thefront bar and 3 the rear bar thereof, and upon the side bars 1 at therear of the front bar 2 is the transverse supporting bar 4. Secured tothe bars 2 and 4 in any suitable manner is the tongue 5 rigidly securedto the frame of the machine by the brace bars 6, the tongue being alsoprovided with the usual draft appliances 7.

Arranged upon the supporting bar 4 at each side of the inner ends of thetongue 5 are the vertical supports 8, and arranged upon the rear bar 8of the frame are the two vertical supports 9 upon the upper ends ofwhich and the supports 8 is arranged the platform or seat 10, and alsoarranged upon the rear bar 8 is the foot rest 11 supported by the bracerods 12, which rods extend upwardly and engage the upper surface of theplatform or seat 10 for retaining the same upon the vertical supports 8and 9 respectively.

Arranged within the frame and adjacent each of the side bars 1 are thewheels 18 provided with the spokes 14 the inner ends of which aresecured to the hubs 15, preferably square, though the same may be roundif so desired, the hubs 15 being provided with the stub shafts 16 eachmounted in suitable journals arranged in the lower edges of the sidebars 1 of the frame.

Secured to the peripheries of the wheels 13 in any suitable manner andextending transversely of the machine Vfrom wheel to wheel are aplurality of cutting knives 17 each provided with the cutting edge 18,the edge 18 being formed by outwardly beveling the blades 17 for themore eiiicient engagement with the ground. The knives, which are hereshown as three in number, are each provided with the brace bars 19 theinner ends of which are secured to a common pivot member 20 arranged inthe plane of the axial alinement of the wheels 13, these ranged upon theprojecting end thereof the hinge member 22 in which is pivotally mountedthe. locking lever 23 through the' medium of the bolt 24C passingthrough the ears of the hinge member 22' and one of the series ,ofapertures 25 formed in the locking lever 23" in proximity to' the lowerend Y thereof., Upon the lower extremity of the lever 23'4 is providedthe lug or hook 25 whiclr'is designed to engage the back of one of tlreknives 17 for preventing thev rotation of lthe Vwheels 13 formaintaining one of the plurality of the knives' in constantengagen'ie'nt with' the ground. y

The locking lever 23v projects upwardlyA and extends through elongatedslot 26 formed in the forward end of the platform or seat 10 and hasarranged at its upper end a series of apertures 27 and connected to thelever 23 is' the link 28 pivotally connected to th'e' lever 2'3 throughthe medium of the bolt 29 passing through one of the apertures 27. Theopposite end of the link 28 is pivotally connected through the medium ofthe pivot bolt 3G passing through one of the series of apertures 31formed in the upper end ofthe rocking lever 32, the lever 32 beingprovided with therock shaft 33' suitably mounted upon the upper side ofthe platform or sea-t 10 by any 'suitable means as shown at 34.' Therock shaft 33 is provided with the depending arm 35 the lower end ofwhich is bent to form the foot rest 36.'

For normally holding the locking lever 23 in engagement with certain ofthe knives 17 isl the spring 37 having one end attached to the pivotbolt 30 and the opposite end secured upon the upper face of the' seat10. For maintaining the locking lever 23 out of engagement with theknives 17 the hook 38 is provided for engaging the lever 23 andretaining the same rearwardly within the slot 26. v

Adjacent the rear end of the side bars 1 of the frame are provided theeye bolts 39 for attaching a harrow or other pulverizing means theretofor pulverizing and smoothing the land in the wake of the cutting knives17.

When the machine is in active operation in the field the locking lever23 engages the rear. of one 'of the knives 17 through the medium of thehook or lug 25 for preventing the rotation of the wheels 13 thuspositioning 'one ofthe'knives 17 in engagement with the ground, thelever 23 being held in normal operative position through the medium ofthe retractile spring 37 for forcing the upper end of the leverforwardly. y For regulating lever 23 is provided with a series ofapertures 25,1501" adjusting the height of the hook 25r for lowering thelocking posit-i011 0-f the knives the lever 23 and the apertures 31 in*the upper end of the rocking. lever 32' for" the more pesan@ egagementtherewith. i

For preventing: the' choking of the' Inachne when operating in foulland, Ii have provided@ the roet leveren positioned within easy reachlof the'y operator of the machine, and by forcing? the' foot lever 36forwardly, the rock lever 32v and the connecting link 28 necessarilydraws the` upper end of lever 23 in aV rearward direction thusfunlocking the hook or lug 25 from engagementwitlr the knife 17, whichlmovement permits the wheels 13 to revolve until the hook 25" of thelocking lever 23 engages the next succeeding knife which is accomplishedby the lremoval of the foot from the foot' lever 36 due to' the actionof the retractile spring 37 foreing. the upper endof lever 23r again inits forward 1.7 may also be adjusted the cliag Y ingl of the link 28`within the apertures 27 of Vthe depth of the knives 17 in the ground,the i Y direction, thus preventing. the choking of the machine in aready and eiicientmanner.

VVh-ile I have here shown and described the preferred embodiment of myinvention, I hereby reserve the right to make such alten ationsandvariations therein as I may deem expedient but which will neither departfrom the spirit of this invention nor conflict with the scope' of theclaims.

Having thus fully described my invention, what I claim as new anddesireI to secureby Letters Patent of the United States is:
